Unfortunately, I lost links of all of them, because my browsing history got deleted unexpectedly. All of the above questions, couldn't help me. Either, some of them have used CELERY or some of them SCRAPYD, and I want to use the MULTIPROCESSISNG Library. Also, the Scrapy Official Documentation shows how to run multiple spiders on a SINGLE PROCESS, not on MULTIPLE PROCESSES. None of them couldn't help me, and hence I decided to ask this question. After several try

It'll have an xmlrpc interface as usual so I can easily communicate with it and have other processes interchange data with it as needed. This daemon needs to access a database. We've been using SQL Alchemy in place of hard coding SQL strings for our latest projects - those mostly done for web apps in Pylons. We'd like to do the same for this app and re-use library code that makes use of SQL Alchemy. So what to do? Well of course since that library was written for use in a Pylons app it's all

My scrapy spider is also working fine. I installed twisted: sudo apt-get install python-twisted Then, I created a sample program using Echo Server code shown here Here is the code from twisted.internet import protocol, reactor class Echo(protocol.Protocol): def dataReceived(self, data): self.transport.write(data) class EchoFactory(protocol.Factory): def buildProtocol(self, addr): return Echo() reactor.listenTCP(1234, EchoFactory()

Effect I wanted to achieve is in the picture. 回答1: Most easiest and neat solution would be to use svg to create the border. #container { position: relative; width: 200px; height: 30px; } #content { text-transform: uppercase; position: absolute; width: 200px; height: 30px; top: 0; text-align: center; line-height: 30px; } lorem ipsum You could even spice it up with some curves using quadratic curves. #container { position: relative; width: 200px;

I installed Twisted with conda install twisted , and now I'm trying to run twisted (or twistd ?) from the console, but I get this error 'twisted' is not recognized as an internal or external command, operable program or batch file. which makes me think a directory is missing from the path, as in this question . Anaconda is installed in C:\Anaconda3 , but even in C:\Anaconda3\Lib\site-packages\twisted , there isn't a twisted.py or twistd.py file. Am I doing something wrong, or am I looking in the

I'm working at a web application in Python/Twisted. I want the user to be able to download a very big file (> 100 Mb). I don't want to load all the file in memory (of the server), of course. server side I have this idea: ... request.setHeader('Content-Type', 'text/plain') fp = open(fileName, 'rb') try: r = None while r != '': r = fp.read(1024) request.write(r) finally: fp.close() request.finish() I expected this to work, but I have problems: I'm testing with FF... It seems the browser make me wait until the file is completed downloaded, and then I have the open/save dialog box. I expected the

I wanna be able to run multiple twisted proxy servers on different directories on the same port simultaneously, and I figured I might use flask. so here's my code: from flask import Flask from twisted.internet import reactor from twisted.web import proxy, server app = Flask(__name__) @app.route('/example') def index(): site = server.Site(proxy.ReverseProxyResource('www.example.com', 80, ''.encode("utf-8"))) reactor.listenTCP(80, site) reactor.run() app.run(port=80, host='My_IP') But whenever I run this script, I get an Internal Server Error, I'm assuming because when app.run is called on port
